I have the opportunity to obtain either a Soundcraft 200B for $200-250 or a Yamaha RM800 ($250-300)both 24 channel. Just wondering if any of you have experience with either of those mixers and which one would you prefer for a recording situation. Is the Soundcraft 200B more of a live mixer? Which one sounds warmer? which has less noise?

If you like multitracking then RM800 is for you, because it has dedicated tape outputs and inputs, plus 8 busses, which is quite unusual for that class of mixer. 200B is more of a downmix device. I heard a lot of good things about RM800, although I have never owned one - it's actually quite rare on a second-hand market. Apparently the only downside are EQs, which are pretty much colorless - although in certain situation that might not be a downside at all.
